签名变换与Clifford代数

Signature Change and Clifford Algebras

David Miralles, Josep Manel Parra, Jayme Vaz

摘要:

给定具有给定签名的二次空间的实Clifford代数,我们在此结构中定义了一个新的乘积,使得它模拟具有与原始签名不同的另一签名的二次空间的Clifford乘积。在这个新乘积的可能应用中,我们用它来写出欧氏时空上的闵可夫斯基狄拉克方程,并定义一种新的对偶运算,根据这种对偶运算,人们可以找到闵可夫斯基时空上规范场的自对偶和反自对偶解,类似于欧氏时空上的自对偶和反自对偶解,而不需要对原来的实代数进行复化。

英文摘要:

Given the real Clifford algebra of a quadratic space with a given signature, we define a new product in this structure such that it simulates the Clifford product of a quadratic space with another signature different from the original one. Among the possible applications of this new product, we use it in order to write the minkowskian Dirac equation over the euclidean spacetime and to define a new duality operation in terms of which one can find self-dual and anti-self-dual solutions of gauge fields over Minkowski spacetime analogous to the ones over Euclidean spacetime and without needing to complexify the original real algebra.
